Realtek为网络接口卡提供网络诊断实用程序 - 在Software Drivers&Utilities中查找“Windows Diagnostic Program”链接。Realtek以太网诊断软件的软件有一些屏幕截图。
Microsoft Windows附带的netstat命令提供了一些有限的信息。一个netstat -s
命令将提供错误的一些附加信息。例如,关于碎片问题的可能性,存在“数据报失败碎片”计数。

您可以使用-p
选项按协议过滤显示。Ping依赖于它发送的“回应请求”的ICMP,因此您可以只查看ICMP的统计信息netstat -s -p icmp
,但这只会给您一个错误计数。
c:\>netstat -s -p icmp

还可以netstat -e
选择查看以太网统计信息,它可以与-s选项结合使用,但这也只会给您一个错误计数。
